Description
Recombinant Human Transforming Growth Factor beta 1 is produced by our Mammalian expression system and the target gene encoding Ala279-Ser390 is expressed.
Alias
Transforming Growth Factor Beta-1; TGF-Beta-1; Latency-Associated Peptide; LAP; TGFB1; TGFB
Endotoxin Testing
Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.
Purity
Greater than 95% as determined by reducing SDS-PAGE.
Activity
Measured by its ability to inhibit the IL-4-dependent proliferation of TF-1 mouse T cellsThe ED50 for this effect is less than 0.2 ng/ml
Formulation
Lyophilized from a 0.2 μm filtered solution of 50mM Glycine, 150mM NaCl, pH2.5
